Positive Grid BIAS FX Metal Tones (and more!)

By Jason Stallworth

May 14, 2019

Are you struggling with dialing in a metal tone using BIAS FX? (here’s where you admit you have a problem so we can fix it!)

In this post, I’m going to give you my exact amp, EQ, and effects settings for my metal tones using Positive Grid’s BIAS FX plugin. 

In fact, I’m going to give you my settings for 2 albums I recorded using BIAS FX, and several other tones.

Go grab your guitar, pull up your DAW and load BIAS FX into a new tracks…we’re going to get to work! 

What Is BIAS FX?

If you already own or are at least familiar with Positive Grid BIAS FX, then you can skip this section and start with the 92 Treadplate tone below.

But if you’re a newbie to BIAS FX, or the world of amp VSTs and plugins in general, I want to give you a short rundown…

BIAS FX is a virtual amp modeling simulator, also called a plugin or amp sims. These amp simulators are designed the mimic the sound, tone, and feel (although that last one is a stretch) of a real amp.

BIAS FX contains a generous suite of amps, and also comes with cabinet, speaker, and effects simulators. So you pretty much have an entire rig with multiple tones at the mercy of your keyboard.

Amp sims used to suck! Big time! But over the years, technology has come a long way. And in my opinion, Positive Grid is one of the leader’s of this bunch. 

Amp Sims for Newbies (Video)

If amp sims and plugins is completely uncharted territory for you, then I have a video on how to use plugins…this will help you get started:

BIAS FX 92 Treadplate

The 92 Treadplate amp sim was hands-down the reason I decided to purchase the the BIAS FX desktop pro package. I was looking for a good Mesa tone and at that point, and the other amp sims I was using just wasn’t cutting it.

***Oh, I used the ’92 Treadplate for my 2nd studio album Heavy Metal Workout (more on that below!)

Now, I’m not saying the 92 Treadplate sounds and feels like a playing through a real Mesa Boogie Dual Rectifier (this is the amp it’s modeled after). In all reality it probably doesn’t.

But I personally don’t care about replicating a sound. If it’s in the ballpark range and the recorded is tight, and more importantly, if it sits well in the mix, then I’m happy.

So don’t get caught up in the ‘it doesn’t sound like a real amp’ syndrome. The question you should ask it does it sound good, period! 

I’m going to spend a little more time on the 92 Treadplate because it has been my go-to BIAS FX amp out of the many metal amps available in BIAS FX. 

The ’92 Treadplate will replicate metal tones from bands like:

  • Megadeth
  • Metallica
  • Slayer
  • Testament
  • Exodus
  • Overkill

92 Treadplate Settings

Below are my basic metal rhythm settings. In fact, my settings are similar across the board. I don’t generally make huge variations.

I cut the bass back to give room for the bass guitar and kick drum. Mids are cut a little but not overdone. On this particular amp model (BIAS FX Treadplate or any Mesa sim), I end up cutting the presence back quite a bit.

Amp Settings

  • Gain: 6.5
  • Bass: 4.5
  • Mid: 4.5
  • Treble: 6
  • Presence: 3.5
  • Master: 5

Cab and Mic Settings

  • 4×12 Treadplate cabinet with SM57 mic sim

  • 4×12 Treadplate cabinet with C414 mic sim

**the 2 cabs/mics are explained below…

Effects Used

  • Noise gate
  • Tube screamer

More on Cabs and Mics

I encourage you to play around with the mic placements. This is where you’ll get the most variations of metal tones. Also try different cabinets and see how that sounds. 

In fact, I use the SM57 mic for one track and the C414 for the other (I generally record two rhythm tracks and hard pan each).

And I sometimes use the Orange cab with the SM57 for leads…that really allows your guitar solos to stand out and cut through the mix! 

More on Effects and Leads

I don’t typically use a lot of effects for rhythms other than a noise gate and tube screamer sim. For leads, I’ll throw in delay, and now and then a little reverb. But there’s a ton of effects you can mess around with in BIAS FX.

I wanted to touch on my leads using 92 Treadplate Mesa Dual sim.

My settings are the same as my rhythms other than a slight boost on the a few things. I boost the gain to about 7-8, bass to 5 or so, and mids are boosted to a little over 6. And I’ll add the delay.

**For effects and leads, this applies to everything (so I won’t replicate this on the amps below). But just because I take the simple way on these things doesn’t mean you have to!

Album Using BIAS FX 92 Treadplate

Heavy Metal Workout World's First Instrumental Metal Workout Music Album

I used the BIAS FX ’92 Treadplate amp sim for my album Heavy Metal Workout. 

This is an instrumental classic metal style album with lot of riffing and chunky rhythms, which the 92 Treadplate worked perfectly for!

  • BIAS FX Insane Satan

    After recording my first album with the ’92 Treadplate I had decided to continue using BIAS FX for another album. But I wanted to find a different tone…a more darker tone!  

    That ended up being the BIAS FX Insane Satan amp sim. 

    For starters, I’m not a big fan of using anything named ‘Satan‘ but I decided to put any superstition aside and just go with what I thought would fit the album.

    I’m fairly certain the Insane Satan is modeled after the Randall Satan (if I weren’t so lazy I would just look that up, and I’m pretty sure that I have before but forgot!)

    The Insane Satan will give you metal tones from bands like:

    • Arch Enemy
    • Ensiferum
    • Dark Tranquility
    • At the Gates
    • Insomnium

    Insane Satan Settings

    Below are my Insane Satan amp settings. It’s important to note that I was looking for a darker tone, but also very tight because there’s a lot of fast alternate picking on the album I used this tone for.

    You may find these settings to be a melodic death metal tone. And there’s a tremendous focus on the cabinets for these tones, which I’ll go into more below. 

    Amp Settings

    • Gain6.7 – This amp sim doesn’t require a ton of gain. It’s designed as a super high gain amp, so you actually get more clarity with the back backed off.
    • Bass5.4 – I felt the Insane Satan needed a slight boost in bottom end, but I didn’t overdo it. 
    • Middle5.3 – I normally cut my mids, but this amp has a sweet spot with the mids slightly boosted. 
    • Treble6.5 – The treble setting was standard for me, although slightly back off from my normal 7. 
    • Presence4.7 – This amp sounds best with the presence up the middle, slightly backed off. 
    • Master5 – Up the middle for the master volume is par for the course. I keep my settings simple!

    Cab and Mic Settings

    • 4×12 ENG cabinet with SM57 mic sim 

    bias fx eng cab sim sm57 mic sim

    • 4×12 Thrasher cabinet with SM57 mic sim

    bias fx thrasher cab and sm57 mic sim

    Effects Used

    • Noise gate
    • Tube screamer

    More on the Cabs and Mics

    You can play around with different cabinets and mics and get some awesome tones. I’m going to give you my favorite combination for the tight tone needed for fast riffing. 

    For one rhythm track, I used the 4×12 ENG cabinet. This is modeled after the ENGL cabinet. If you’re like me, anything that remotely sounds like an ENGL is gonna be killer! 

    The SM57 mic sim pairs up really well with the ENG cab. Scroll up a little to the images and you can see my mic placement. Start there and move it around to where you like it (the ideal tone for you may be different from what I prefer, and that’s ok because no one wants to listen to music that sounds like everything else!)

    For my second rhythm guitar track, I paired the Insane Satan amp with the 4×12 Thrasher cabinet.

    Let me just say this cabinet is a super beast. It’s dark, heavy, and has this growl to it. Yet it’s one of the most clear sounding cabinets from the BIAS FX suite.

    I also used the SM57 mic for the 4×12 Thrasher. I positioned the mic a little closer to the cone than with the 4×12 ENG, as you can see. I did this to help balance the bottom end.

    These two BIAS FX cabs, ENG and Thrasher, are a fierce combination for metal tones! 

    Album Using BIAS FX Insane Satan

    heavy metal workout II instrumental death metal workout music

    Heavy Metal Workout II follows up the original HMW but with faster, more aggressive riffs. 

    This album is an instrumental melodic death metal meets thrash metal album. 

    It required the tight and dark metal tones that the BIAS FX Insane Satan delivers.

  • BIAS FX Snake’s Lead 800

    Now we’re venturing metal to more of a hard rock tone. The BIAS FX Snake’s Lead 800, based on the Marshall JCM800, puts out some pretty solid tones. 

    In the video below, you’ll hear two types of hard rock tones; my rhythm and lead tones. I purposely wrote a piece of music that consisted of chords ringing out as well as choppy riffs because I wanted you to hear the diversity this amp sim has. I did the same with the guitar solos (some notes are milked and there’s some fast soloing too)

    The Snake’s Lead 800 amp will general tones from bands like:

    • Guns ‘n Roses
    • Dokken
    • Scorpions
    • Queensryche
    • DIO
    • (most of the hair metal bands!)

    Snake’s Lead 800 Video

    Snake’s Lead 800 Settings

    What you see above is my standard rhythm hard rock guitar tones with the Snake’s Lead 800. My lead tone isn’t much different. I crank the gain a little and add just a hair more bottom end, and usually bring up the mids as well.

    I also use delay for my guitar solos (and occasionally on rhythms if I’m going for an 80’s hair metal sound! And do NOT even pretend for one minute that you don’t like hair metal!)

    Amp Settings

    • Gain: 7
    • Bass: 5
    • Mid: 6
    • Treble: 7
    • Presence: 6.7
    • Master: 8

    Cab and Mic Settings

    • 4×12 V75
    • SM57 mic

    Effects Used

    • Tube screamer
    • Delay
    • Reverb

    More on the Snake’s Lead 800 Tones

    The BIAS FX Snake’s Lead 800 amp works extremely well with simple settings. You can start with my amp and EQ settings above, or just start with everything up the middle and tweak from there.

    It might sound like ‘Duh’ but the heavier your music is, the more gain you’ll want from the amp. In fact, don’t be afraid to crank it all the way up. Because the Snake’s Lead 800 does not carry the amount of gain as, let’s say, the 92 Treadplate.

    You will probably want to put the tube screamer sim (or some sort of overdrive sim) in front of the amp. Especially if you’re using more gains. This will tighten up the tone.

    The beauty of the Snake’s Lead 800 is you can back off the amp’s gain and get some really cool tones. It’s an extremely diverse amp sim. 

    Other Great BIAS FX Rock and Metal Tones

    Of course there are more BIAS FX amp models you can use for rock and metal. I just gave you my personal favorites above.

    Below you’ll get to see (and hear!) some other cool tones!

    ’04 Insane 5153 Video

    I came very close to using the o4 Insane 5153 amp instead of the ’92 Treadplate for my Heavy Metal Workout album. 

    Mark IIc Video

    I didn’t mess around with the Mark IIc amp much until later. And to be honest, I rarely use it. But listening to the video below, it does put out some cool metal tones. 

    British Rock 50 Video

    There’s just something about this tone that I absolutely love, even though I rarely use it (because it’s not geared for metal).  

    TIP: Try pairing the Orange cab with a high gain metal amp, as I mentioned earlier! 

    Clean and Ambient Tones

    This may be one of the most interesting BIAS FX tones you’ve heard (kinda like that most interesting dude in the world that promotes Dos Equis beer!)

    What Are YOUR Final Thoughts on Positive Grid BIAS FX?

    I’d be willing to bet you’ve played through your fair share of amp sims and plugins. Their convenient, and most of us don’t have ideal situation to crank up a half stack. 

    The problem has been finding an amp sim that sounds realistic. To me, Positive Grid’s BIAS FX comes very close. And in reality, most people aren’t going to be able to tell if it’s a real amp or plugin. Think about it…even when real amps are recorded, they go through some sort of digital processing after the fact. 

    I guess it’s obvious how I feel about BIAX FX, having use their amps for 2 albums. But I’d like to know your thoughts.

    What’s your favorite BIAS FX amp sim? What’s your least favorite? Leave a comment below!

    Keep it Metal,
